SPECIFICATION forming part of Letters Patent No. 620,148, dated February 28, 1899.

Application tiled December 22, 1897. Serial No. 662,990. (No model.)

To a/ZZ whom i may concern:

Be it known that I, JOHN GEORGE AULsE- BROOK KITCHEN, a subject of the Queen of Great Britain, residing at Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Acetylene-Generators, of which the following is a specification.

This invention relates more particularly to portable generators for use in connection with table, vehicle, and hand lamps and with small power internalecombustion motors, such as are used for propelling wheeled vehicles and boats; and it consists in improvements in and connected with the construction of such generators with the object of producing an ineX- pensive and simple apparatus which will not be affected by vibration.

In a generator constructed in accordance with my invention there is a closed chamber, of metal or of other suitable material, which has a removable door o r cover, and inside this chamber is disposed a perforated receptacle or basket to receive the calcium carbid and which is made readily removable. There is an orifice formed in the lower part or in the bottom of the chamber, and there is connected to this orifice a collapsed chamber, preferably principally formed of india-rubber or other suitable flexible material, so as to be capable of considerable expansion. The outlet-pipe for the gas is led from the upper part of the generator. There is a tap or other indicator for the reactionary liquid below the carbidreceptacle.

The sheet of drawings attached hereunto illustrates a generator constructed in accordance with my invention.

In the said drawings, Figure l represents a sectional elevation of the generator, and Fig. 2 a plan on the line x.

The generator consists, first, of a chamber or vessel c, having a gas-tight lid a2 at the top, shown as screwed upon the casing a, and having a flexible washer 0.3 in order to obtain a tight joint. The lower part of the casing ct is fixed to a box-stand c', which forms a bottom for the vessel a. A collapsed indiarubber chamber b is fixed in the box-stand gas through the orifice f.

.means of the knob b4.

or cover a2 fastened down.

a by means of a screw b passing through the bottom of the vessel a, fitted with a nut b, and having a hole b3 passing through, by which screw and nut the india-rubber chamber is clamped to the vessel a. A knob b4, tapped and provided with a screw b5, is screwed by clamping to the outer wall of the flexible india-rubber chamber b. A receptacle or basket c, perforated preferably all over, is formed to fit loosely in the vessel a, leaving some space between itrand the bottom of the vessel, as illustrated. Preferably a loose tray d is placed under the receptacle c and rests upon projections d upon the bottom of the vessel a. There is a Water-level indicator, preferably in the form of the tap e. This is left open while the chamber b is filled or partly filled with water, so that the level remains below the bottom of the vessel c. A tap f is fixed to the lid a? for taking off the In order to prevent the liquid from flowing into contact with the carbid in the vessel c in the event of the apparatus becoming upset, a shield gis fixed to the inside of the casing a in the manner shown in the drawings, and thereby a chamber is formed in which the liquid will be trapped.

The water will, when the lamp lies on its side, surround the outside of the shield g, but will not go past its end, which is water-tight, within the casing a. In practice the space between the said shield and the casing a should be large enough to hold all the water that might otherwise enter the lower opening of the shield and then attack the carbid.

Water is introduced into the vesseld after the lid c2 and the vessel c have been removed. The water is allowed to partly ll the chamber b by expanding the latter by When the level coincides with the tap e, the vessel c, charged with granulated carbid, is introduced and the lid By releasing the knob and allowing the chamber b slightly to contract water is forced into contact with the carbid in the bottom of the receptacle o and gas is immediately produced, whichv if not taken off as generated will act upon the surface of the Water and force it back into the chamber b. As the pressure of the gas produced falls, due to being consumed or drawn away from the generator, Water is forced out of the chamber b, as the latter tends to as- 'sume its normal form, and again comes in contact with the carbid in the receptacle c, gas being again produced, the pressure of which again forces back the Water into the chamber b. This operation is repeated until all the carbid or all the Water is decomposed. The tray d serves to receive the residue of the decomposed carbid,which passes through the perforations in the bottom of the receptacle c.

The generator shown may be used as a vehicle-lamp by fixing thereto a carrier of the usual Well-known form and placing a glazed hood over the burner,which maybe arranged in front of the casing a by carrying a pipe from the outlet-orifice thereto.

I do not confine myself to the particular form of the apparatus illustrated or to the relative position of the chamber b,which may equally Well be applied at the side of the chamber or vessel a, as long as the parts are arranged to fulfil the functions required of them, as hereinbefore set forth.

I claim as my invention- 1. A generator for producing acetylene from calcio carbid and Water consisting `of a gas-tight vessel to contain Water having ,a hollow base, a iieXible collapsed chamber in the base communicating with the said Vessel, a perforated carbid-receptacle loosely fitted into the said vessel, a shield for preventing the Water from coming into contact with the carbid in the carbid-receptacle in the event of the apparatus becoming upset and an outi let-orifice closed by a tap said shield surrounding the lower part of the carbid-receptacle.

2. A lamp consisting of the combination of an expansible and contractible receptacle of india-rubber for containing a liquid, a vessel for holding the product to be acted upon by the liquid, an air-tight chamber for confining the gas liberated by the liquid from said product, means for permanently permitting the passage of the liquid to and from the expansive receptacle, to and from said vessel by the action of the pressure of the gas produced and a tap for the exit of the gas, and a tap e arranged in the side of the chamber for gaging and xing the depth of the liquid.

3. A lamp consisting of the combination of an expansible receptacle for containing aliquid a vessel for holding the product to be acted upon by the liquid, an air-tight chamber for confining the gas liberated by the liquid from said product, means for permanently permitting the passage of the liquid to and from the expansive receptacle to and from said vessel by the action of the pressure of the gas produced and a tap for the exit of the gas, and a tap e arranged in the side of chamber for gaging and fixing the depth of the liquid, a knob b4 being attached to the expansive receptacle for manually expanding the same.

In testimony whereof I have hereunto affixed `my signature in the presence of two Witnesses.
